Title: Improvements relating to derrick cranes and like derrick hoists
Inventor: VONCK WILLEM FREDERIK
IPC: B66C23/687
Filed: 1967-11-28
Abstract: 1,253,815. Telescopic jib cranes. W. F. VONK. 25 Nov., 1968 [28 Nov., 1967], No. 54144/67. Heading B8B. A crane includes a derricking jib 3 of four telescoping sections 21, 22, 23, 24, of successively increased square or triangular cross-sections, with a jib extension cable 30 to vary the jib length. As shown, the derricking cable comprises a fixed length 12 extending between the top of the jib 3 and a pulley 13, and a variable length portion 10 including a cable 14 passing over pulleys 13, 15, 42 and jib-telescoping winch 40 to become integral with the jib extension cable 30. The jib 3 may be raised or lowered by operating a derrick winch 17 to take in or pay out cable 16 attached at one end to the pulley 15, the three runs of the cable 14 between the pulleys 13, 15 giving a mechanical advantage. The jib 3 may be extended or contracted by operating the winch 40, the cable 30 between adjacent jib sections, e.g. sections 23, 24 as shown in Fig. 2, passing around pulleys 31 to 35, of which 32, 35 are fixed to the section 24 and 31, 33, 34 are attached to the section 23. Thus, if the cable 30 is taken up the three runs of cable respectively between pulleys 35, 34; 33, 32 and 32, 31 will all be shortened giving a mechanical advantage. As the cables 30 and 14 are integral the jib 3 may thus be extended or contracted by the winch 40, the change in length of the cable 30 being substantially commensurate with the change in length of the cable 14 without the necessity of operating the derricking winch 17.

In an automatic choke or starting carburetter comprising a bimetallic coil 6 rendered inoperative after cold starting by an electric heating resistance 7, a thermally responsive resistance 17 responding to engine temperature is arranged in the circuit of resistance 7 to increase the current through the heater 7 as engine temperature increases. In Fig. 1 the resistance 17 is in series with heater 7 and is responsive to engine cooling water or lubricating oil temperature, the resistance decreasing as engine temperature increases until at normal engine temperature the heater 7 is sufficient to cause coil 6 to fully open the choke valve 8. In Fig.3 (not shown) the resistance 17 is in parallel with heater 7 and its resistance increases with rising temperature.

Abstract: 1,175,687. Diffusion apparatus. E. I. DU PONT DE NEMOURS & CO. 13 Dec., 1966 [22 Dec., 1965], No. 55708/66. Headings B1L and B1X. Diffusion apparatus 100 comprises cylindrical housing 101 within which are tightly packed a large number of hollow filamentary membranes 111 sleeved in a plurality of flexible porous members 112, all bundles being enclosed in flexbile porous sleeve 113. At each end, the filaments pass through cast wall member 950, which provides a fluid-tight end wall to the volume lying within housing 101 but external to the filaments. The internal face SF of the wall member is cylindrically concave. The filaments consist of a suitable polymeric material, polyethylene, terephthalate being preferred, and have a diameter of 10-500Á, with a uniform wall thickness of 1-100Á. Feed is passed to inlet 104, and effluent leaves through the corresponding outlet 104 at the far end of the housing. Permeate which passes through the filamentary walls is swept from the housing through outlet 108 by sweep fluid entering through inlet 109. Fig. 6 (not shown) illustrates a two-stage diffusion system suitable for use in obtaining oxygen-enriched air, or for separating hydrogen or methane from mixtures thereof with other gases, in the first stage of which a fraction of the feed is used for the sweep medium carrying the first stage permeate to the feed input of the second stage. The system embodies automatic control for keeping the overall composition of permeate and effluent constant.

Abstract: 667,990. Cycles; cylinder heads; supplying liquid fuel; regulating.. COOPERBESSEMER CORPORATION. Feb. 28, 1950 No. 5063/50. Classes 7(ii), 7(iii) and 7(vi) In a four-stroke engine passages 10, 9 from low-pressure supplies of permanent gas and air respectively are controlled by cam-shaft operated valves 19, 11 in such a manner as to initiate air admission before the completion of the exhaust stroke and gas admission during the suction stroke to give a mixture some 25 per cent weaker in gas than a chemically perfect mixture and which, after compression without ignition to a pressure which would spontaneously ignite such a chemically perfect mixture, is ignited by the injection through a nozzle 35 of a small quantity of liquid fuel such as oil. The initial pure air admission may effect scavenging, and the valve 19 closes before the valve 11 at the end of the suction stroke to clear the passage 9 of combustible mixture. As applied to a multicylinder engine, the air inlet manifold 1 is supplied by a turbo or other blower 2 and the engine is regulated by an engine-driven fly-ball governor 38 controlling a valve in the supply pipe 4 to the gas inlet manifold 5. Alternatively, a similar governor could be used to control the period of opening of the valve 19. The oil injected preferably represents less than 10 per cent of the total heat value of the fuel, and may be kept constant in quantity at different loads. The permanent gas fuel used may be natural gas or coke-oven or other by-product gases.
